How Capital Gains Tax Applies to UK Property Sales

Capital Gains Tax (CGT) is a levy you must pay on the profit earned when selling a second home, rental property, or investment property in the UK. It applies when the asset has increased in value and is not your main residence. This tool simplifies CGT calculation by helping you figure out your tax liability based on sale price, purchase price, costs, and income level.

When Does CGT Apply to Property?

CGT is due when you sell or dispose of a property that is not your primary residence. Common scenarios include:

• Selling a second home
• Profit from buy-to-let or rental property
• Inherited properties sold at a profit

What Are Allowable Costs?

Allowable expenses that reduce your CGT liability include:

• Legal fees during purchase or sale
• Stamp duty and estate agent fees
• Improvement and renovation costs

Current CGT Rates

• 18% for basic rate taxpayers (income up to £50,270)
• 28% for higher/additional rate taxpayers

How This Calculator Works

This Capital Gains Tax calculator factors in your income, asset value, and HMRC allowances. By inputting your sale and purchase price, improvement costs, and salary, it estimates the tax you’d owe. It considers the annual CGT tax-free allowance (e.g., £6,000 in 2024–25).

Reduce CGT Legally

• Use your CGT allowance before year-end
• Transfer ownership between spouses for tax relief
• Deduct all eligible expenses and fees
• Time the sale across tax years for split gains
